In which state of matter do particles have the least kinetic energy?

In which state of matter do particles have the least kinetic energy?

Step 1: Understand what kinetic energy is. Kinetic energy is the energy of motion that particles have.
Step 2: Identify the three main states of matter: solids, liquids, and gases.
Step 3: Compare the movement of particles in each state. In solids, particles are closely packed and can only vibrate in place.
Step 4: In liquids, particles are less tightly packed and can move around each other, giving them more kinetic energy than solids.
Step 5: In gases, particles are far apart and move freely, resulting in the highest kinetic energy.
Step 6: Conclude that since particles in solids vibrate in fixed positions and are closely packed, they have the least kinetic energy compared to liquids and gases.
